ArrayCollection column counts

Posted on by — No Comments ↓

As part of an example of trying to read data from SharePoint and display it in a Flex/Flash application, I needed to see if I could create pie charts from the data.  After figuring out how to get the list data as an xml output, then cleaning up the data to insert it into a ArrayCollection, the next step was to count the number of times a particular value was used in a particular column.  If I was using SQL, it would be  a straight forward grouping and count.  The work around was to filter out the unique values and Continue reading ArrayCollection column counts→

Orientation change with MXML

I have been banging my head on the wall trying to figure out how to detect the device orientation on the BlackBerry PlayBook.  I initially tried to use the accelerometer function.  Unfortunately, the listener would continue to activate and determining the exact orientation was a little iffy.  So, a slight move of the device would set off the listener and the redrawing of the screen would keep going until the accelerometer stopped.  This was not a good way to test for orientation, it will be a great way to make a game that required moving the PlayBook around a lot.  Continue reading Orientation change with MXML→

Simple Countdown Timer

Posted on by — No Comments ↓

After creating the simple Egg Timer application, I made some changes to make it a little more flexible. The original Egg Timer was just a 1 or 2 minute timer that just showed the time elapsing. The new Countdown Timer does the same, but also adds 15 second and 10 second markers to the timer and allows for selection of different time periods. I also made changes to a simple clock counter that I created. The original clock counter would count up from a specific time. I made a change to set it to count down or up. Adding the Continue reading Simple Countdown Timer→
